Car Stall problems of the 2018 Buick Enclave

Shortly after getting gas, the car will rev to 2-3rpm when lightly accelerating, and seem to "run rough". Then, after coming to a stop at a traffic light, the car will auto stop and then shift into neutral. I can not shift back into drive without pushing the start/stop button to restart the car. It does not happen every time I get gas, but all 3 times it has happened have been after getting gas. The first 2 times it happened, I was told there was a recall, which was the cause, but this last time, there was no recall, and they said there were no error codes, so they do not know what is wrong. The car stalling episodes occurred in August 2019, September 2019, and February 2020. It may or may not be related, but in October 2019, there were also 2 instances of an "evap leak" that were fixed.
